Text Messages Why can I not write text messages from my TomTom 910? It says feature not supported.

There are two ways to listen to your text messages on iPhone:

• By using Siri, simply give Siri a command such as "Read my text messages" or "Read my latest text messages".
• By turning on the Speak Selection function in Settings > General > Accessibility > Speech and then tapping your messages.
